Westminster ‘Big Ben’ material authenticity, or lack thereof
The clock tower, Palace of Westminster, London, popularly known as Big Ben, was originally built of Magnesian Limestone. Stone from Bolsover Moor quarry was used for the plinth with Anston Stone above. About 50 per cent of the stones above the plinth have now been replaced with Clipsham Stone.
Is it better to maintain original materials or replace them with a more sustainable alternative?
